Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12164, here are decompositions:
- 3 + 12161 = 12164
- 7 + 12157 = 12164
- 67 + 12097 = 12164
- 127 + 12037 = 12164
- 157 + 12007 = 12164
- 193 + 11971 = 12164
- 211 + 11953 = 12164
- 223 + 11941 = 12164
Showing the first eight; more decompositions exist.
